Our problem is with a SUN 4/260 (which we have just upgraded from a SUN3).
When we try to do *heavy* transferring of files from a disk on the
machine's xylogics 451 controller to a disk on the machine's xylogics 753
controller we get the following message on our console:
spurious VME interrupt at processor level 5
VME level 3, VME vector 0xffffffff
These two lines repeat as quickly as the screen will take them and they
just keep on repeating without stopping. Apparently the machine crashes
when this happens (all it's services stop) but the console keeps repeating
the messages and the only way to get the machine back is to reboot it.
Our setup is as follows:
SUN 4/260
slot 1 -> cpu
slot 3 -> 8 MB
slot 5 -> 32 MB
slot 6 -> 8 MB
slot 7 -> xylogics 472 tape controller
slot 11-> xylogics 753 disk controller (xd0)
slot 9 -> xylogics 451 disk controller (xy0 xy1)
(xd0, xy0, and xy1 are all M2361's)
(we have tried swapping the location of the two disk
controllers, but we are still getting the interrupts.)
We installed OS 4.0 on disk xd0 hanging off the 753 without any problems.
The disks xy0 and xy1 had been previously formatted and partitioned by the
machine when it was a SUN3 using 3.2 diag, and in fact the disk xy0 used
to be the computer's system disk. They above errors are caused when we
try to transfer files from a partition on xy0 to a partition on xd0.
Has anyone seen this problem previously? Does anyone have a similar
configuration that works, or does not work? Also, does anyone know what
the proper settings for a 753/M2361 set-up should be?
Thank You,

Well, I am finally getting to pay back some of the help I have received on this net. We also had this problem in trying to install a xylogics 753/CDC 1.2GB drive combination in a 4/280. What we finally discovered was that the problem was a recently (I was told) discovered problem by xylogics with this combination. They pretty much indicate those exact symptoms (including system crashes that Nassiopoulos later refers to) in the notice I was read by my system integrator tech. The solution is to get the latest rev controller from xylogics (our new board has 753-107-03; I think the -03 is the rev). As I understand it, this is not a problem with sun 3's (we tried a 3/260 board and it worked fine). Hope this helps folks.
